linear bearings

Bearings housed in carriages and tables can ride on round shafts or square profile rails. Here’s a look at the advantages of each when an application demands guided linear motion.”
Engineers faced with a linear-motion application often turn to pre-engineered linear bearings and guides. But linear guides come in two basic shapes – round and square – and designers often struggle with which type to use. Square or profile rails once cost significantly more than round because the former need extensive grinding that is inherent to the design. But recent manufacturing advances and economies of scale let square rails now compete with round in a broad range of applications.

 

The criteria for choosing one over the other are no different than choosing any other machine component: define system objectives, then consider factors such as load capacity, stiffness, accuracy, smoothness, size, and overall costs. The best place to start is to look at the fundamental qualities of each type of guide.

 

 

Linear Ball Bearings are designed to provide a free motion in one direction. These are the most common type of linear slide, offering a smooth precision motion along a single axis linear design. Most commonly used within the furniture industry as a ball bearing drawer slide.
